Priostar dendrimers are core-shell nanostructures with well-defined design and low polydispersity, which are synthesized in a cascade fashion around a core unit, emanating with high level of control over size, branching points and surface functionality. The ability of tailoring dendrimer properties to the needs of a drug makes them ideal carriers for drug delivery. In this study, multidimensional NMR techniques relaxation and diffusion NMR measurements have been used to characterize the structures of these novel priostar dendrimers with carboxyl groups on the periphery, which are very readily soluble in water. Through multidimensional NMR studies, the NMR resonance assignments of the dendrimers can be achieved. Then using relaxation and diffusion NMR measurements, the motion and size of the molecules can be probed.
